The former My Name Is Earl star apparently owes more than $637,000 in deliquent taxes.

According to public records, the IRS filed a $260,370 tax lien on Dec. 6 against the actress, nearly three months after filing another lien in the amount of $281,699 relating to her 2008 income taxes. That's in addition to the $95,080 lien also filed by the state of California on June 21 in L.A.

But that's not the only thing Pressly is having to deal with right now...

The 33-year-old Emmy winner has also reportedly just split from her husband, entertainment lawyer Simran Singh. The two tied the knot in September 2009.

Of course, all this news comes on the heels of her arrest earlier this month on suspicion of drunken driving after being pulled over for a traffic violation. She is currently out on $15,000 bail and is expected back in court on Feb. 7.
